HEATING / AIR CONDITIONING  AIR CONDITIONING SYSTEM(for Manual Air Conditioning System)  SYSTEM DESCRIPTION  

GENERAL

a.

The air conditioning system has the following controls.

Control	Outline
Manual Control	Damper positions and blower speed operate automatically according to the operation of switches such as the temperature control switch, blower switch, mode control switch and inlet control switch.
Compressor Control	Through the calculation of the target evaporator temperature based on various sensor signals, the air conditioning amplifier optimally controls discharge capacity by regulating the opening extent of the compressor solenoid valve.
Diagnosis	A Diagnostic Trouble Code (DTC) is stored in memory when the air conditioning amplifier assembly detects a problem with the air conditioning system.
